IMPROVEMENT IN GRAIN-SEPARATORS.

Specification forming part ofLettel-s Patent No. 40,756, dated December 1, 1863.'

Z'o all whom, it may concern.-

Be itknown that I, LOUIS PIERRE JOSSE, ot' Paris, in the Empire of France, have invented a new and Improved Apparatus for Oleansin g or Separating`Grain or Seeds; and l do hereby declare that the following is a full and exact description thereof, reference being had to the aocompanyin g drawings, and to the letters of reference marked thereon.

The invention relates to an improved apparatus for separating or cleansing wheat, rye, barley, oats, or other grain or seeds, and sep aratc therefromthe chaff or lighter particles and the dust or other impurities, and, if required,vsortin g or separatin gthe grain or seeds in several qualities, according to their specific gravity-- The apparatus consists of a shallow box, by

' preference of 'an equilatcral triangular shape,

the bottom of which is provided all aroundv with a narrow rim, and is mounted either horizontally or in a slightly-inclined position on three or more feet of thin wood, sheet metal, or other Suitable material of sufficient ilexibility for allowing of imparting to the box a more or less rapid horizontal to-andfro or reciprocating motion in a direction parallel to that side of the. box situated opposite the corner by which the grain or seeds take their' exit from the apparatus, by the effect ofwhioh motion the grain or seeds, which, from a hopp perfall into the box, will be continually thrown back from otre to the other of the two remainder sides of the box, and thereby cause the chaff or lighter particles to rise to the top of the grain.- or seeds and' travel toward the first-mentioned side of the box-viz., that situated nearest to .the hopper-whereas the grain, seeds, or other heavier parts will advance toward the corner situated opposite this side-viz., the corner pointing downward, in case a slightly-inclined position be given to the box-and by an aperture provided in this corner fall on proper screens, perforated plates, or sieves, for depriving the grain or seeds of the remainder of the extraneous matters contained therein. The chai' or other lighter particles contained in the grain or seeds rise on the top of these latter, and, traveling in an opposite direction to them, finally fall over a depression provided for this purposein the rim of that side of the box situated nearest to the hopper.

In the inside of the box one or more partitions, of an angular shape, aie fixed to the bottom of the box for thepurpose of conducting the grain toward the exit-opening and operating the separation ot' the chaff or lighter particles.therefrom, while two or more of the said boxes may be connected to'- getherlengthwise or in any other suitable manner, so as. to operate Sixnultaneonsly. The sides ofthe box may also be provided with angular indentations for aiding inthe separa.- tion of the lighter from the heavier parts of the grain or seeds.

l now will enter more fully into thel details of the invention, and refer thereby to the annexed drawings, in which- Figure 1 represents a side, Fig. 2 a l'front elevation, and Fig. 3 a top view, ot' the appa' ratus, while Fig. 4 represents a separate side View ot' the triangular drawer-shaped box and screens connected thereto. "llhe remainder of the figures represents plan views of various modiiieations of the said box.

In all these figures the same letters of rei'- erence show corresponding parts.

Theiapparatus consists, as has been already said above, of a shallow box or boxes, A A

A?, by preference of a triangular shape, aib e,

Fig. 3, but which shape may be modified according to the effects to be obtained, or the nature of the grain or the seeds to be cleansed or separated. around its three sides with 'a narrow rim, d, so as tomake the box assume the form ot' a drawer, mounted either horizontally or in a slightly-incl@I position on three or more feet orstandards, B, in which latter ease the corner c requires to be situated alittlehelow the corners a and b. The lower end of 'the feet B is iixed either to the oor o r to a frame, X, resting on this latter. 'lhe feet or nprights B should be made of strongA sheet'metal, wood, or any other suitable material offering sui cient elasticity for allowing the operator to impart to the box or boxes A A A2 a more or less quick horizontal to and-fro motion in the direction of the arrows 1 and 2, Figs. 2 and 3, so as to cause the grain or seeds to be projected to and fro from one to the other of the sides of the box and of the partitions or angular prisms provided in this latter, which motion causes the chaif or lighter particles to rise on the top of the grain or seeds and travel toward an opening. f, in the side a b, and

The bottom a-b c is provided take their exit by this opening,- whereas the.

grain, seeds, or heavier parts advance toward l cleansed or separated are thrown in-a hopper,

D, fixed by a standard, D,to the 'frame X or to the floor.

vThe delivery of the grain into the box A is regnlatedby a sliding door,-E, worked by a 1 screw, F', 0r by any other suitable means, and, if required, the grain may, fall on a small screen, provided inthe box A, underneath the exit opening di' the hopper, for separating 4 from the grain `or seeds small bits of straw or other similar impurities mixed therewith,"

while by the horizontal to-and-fro motion imparted to the box A the grain is caused to ad- Vance toward the corner c, as has been already mentioned above, and having become cleansed of the lighter parts or thechaii falls on'the screensjH, the yform and size of the pirforations, meshes, or openings of which latter depends on the work to be performed,

Yfor which purposes these screens, sieves, or

vstrainers lH are movable and rest in av small frame ixed to the box. A, so as to allow ol" changingthe said screen when required. VAs has been mentioned abve, the chaff or lighter particles will ascend toward and fall over an opening,`f, provided in the rim of the sidea b ot' the box, where they fall into a proper receiver. This traveling or advancing of they The box A maybe made of Wood, sheetiron, or any otherl suitable material or metal, and its size' may vary according to the work to be performed, while the above-mentioned .horizontal `reciprocating motion maybe imparted to the box A, either by hand or by any suitable prime moverand -connecting ma.-

chinery. At all events the' intensity of this motionamiist be such as to cause the grain or Seeds to be projected from o'ne to the other'of the sides a aand b o of the box, or ot'these sides to those of the prisms or partition plate'cr plates h inserted in this box, the quickness of the motion'being'regulated so as'to obtainthe due separation of the lighter parts or the chaff from the heavier parts of the grain or seeds to be cleansed or separated.

,1n order to prevent the choking up of the exit-opening I of the hopper, an agitator or shaker, J, turning on a pin, i, is. moved to and fro by the effect of the stops j. I further Wish to observe here that the motion to be imparted to the apparatus, instead of being continuous, may be intermittent or varied aceordin g as requisite for obtaining the due separation ot' the lighter from the heavier parts ofthe grain or seeds.

The Figures, 6, 7, 8,9, l0, and 11 show various. modications of the arrangement of the box A.

In Fig. 5 the grain or seeds enter the box at g and arecondu'cted toward the ,rims .a c-

and blc by means of the partitions h and h' and the indented prism or obstacle K, which partitions and obstacles are fixed to the bottom in the interior of the box A and are of the same height as the rim lof this latter.

Theexit of the grain or seeds is shown by the arrows, while the cha' or lighter parts follow the arrows e z and leave the box by the openings f and j?. l

Fig. 6 shows another form lof obstacle, K..

1n Figs. 7, 8, 9, and 10 the sides'a c and b a of the box are provided with angularindentations m and n, the said indentations corre spending together inthe Figs. 7 and 8, while in the Figs. 9 and 10 the angle of each indentation on the side a c of the box is situated opposite the sides of this4 angle in the ,corresponding indentation ofthe opposite side, b c, of the box.

. `In Fig. 9 the box A'is divided in a series of smaller boxes, A A2 Af. By this means the; `greater part of the chaff or lighter particles mixed with the grainor seeds in the ir'st box, A', takes its exit at j?, while the grain enters the second box, A2. The lighter particles or the lighterV grain or seeds in this box A2 are in their turn separated from the heavier ones andtake their exit at f2, while the heavier grain or seeds enter into `the box A3, 'where again the separation between the lighter and the heavier parts takes place. 1t willbe ob' vious, consequently, that byrthis apparatus- .not only the cleansing, lbut also a sorting of the grain or a separating, according to the difference in specific gravity, will take place.

In Fig. 11 two boxes, A5 and A6,' are connected together in one apparatus.

From what has been explained above,it will be evident that a great many more modtications may be made in the shape or arrangement of the box or boxes in which the sepa- .ratin 4of the 1ighter...parts ofthe grainmor seeds or the chaff'` from the heavier` parts takes place, as also in that of the screens,

sieves, orl perforated plates, the hopper, or in:-

the4 general arrangement ofthe apparatus, without departing from the main' feature of the invention, which consists in operating the.

separation of the lighter from the heavier parts by imparting a suitable horizontal reciprocating motion to the box or boxes A,

thereby causing the lighter parts to travel and leave the said box or boxes in an opposite direction to that ofthe heavier parts with. which the same are mixed.

Having thus described and particularly ascertained the nature of the invention and the `fectuated by imparting a suitable horizontal reciprocating motion to a triangularly-shaped shallow box or boxes in which fall the grain or seeds to be cleansed, by the e'ect of which motion, and the configuration of the said box 0r boxes, the chaff or lighter parts rise to the top of the grain, seeds, or heavier parts, and travel and leave the saidl box or boxes in an opposite direction to that of these latter parts, substantiallyas described.
